RENOVATOR FOR CUTLERY.

SPECIFICATION forming part of Letters Patent No. 758,837, dated May 3, 1904. Application filed December 3, 1902. Serial No. 133,724; (No model.)

To all whom it may concern:

Beit known that I, HERMAN HANSEN, a citizen of the United States of America, residing at New York, in the county and State of New York, certify that I have invented a certain new and useful Renovator for Cutlery, &c., of which the following is a specification.

My invention relates to machines used for the purpose of wearing down or g'iving a smooth surface as by the friction of revolving wheels, &c.as, for example, cutlery and the like; and it has for its object the provision of an apparatus of the kind set forth simple in construction, inexpensive to manufacture, and which operates smoothly and efficiently in practical use.

To attain the desired end, this my invention consists in the construction, arrangement, and operation of parts herein set forth.

In order to enable my invention to be fully understood, I will proceed to explain the same by reference to the drawings, which accompany and form a part of this specification, in which Figure l represents a side elevation of a machine constructed according to my invention. Fig. 2 isa plan view of the same. Fig. 3 is a view of the bottom of the machine. Figs. 4 and 5 are views in detail of my dustcatching plate or drawer; and Figs. 6, 7, and 8 are detail views of one of my cleaningrolls.

Like numerals of reference indicate like parts in all the views.

Referring particularly to the drawings, l0 denotes the ordinarily horizontal bed plate or base of my machine, which may be provided with feet of suitable description by means of which the same may be rigidly secured to any suitable support, the said base being also provided with preferably vertical shaft-supporting posts 49, 50, and 51 and also with two roll-supporting posts 66. Upon the base is mounted driving means, as an electric motor 29, of any suitable construction, and which may be provided with binding-posts, as 23, 24, and 25, whereby the same may be connected with any preferable electricity-generating means. The motor-shaft 40 is provided with a gear 41, which meshes with the gear 42, rigidly connected with a pinion 43, which is in mesh with the gear 44, located upon and rigidly attached to the shaft 47, which is joui'- naled in the posts 49, 50, and 51.

I pivot a crank or rockframe 58 to the bottom of the plate lO, the two outer arms projecting' therefrom serving to support the post of the rest 59. The rod is engaged at one extremity with the upwardly-projecting portion of the part 58, and is connected in an adjustable relation with the plate 61, uniting the bottom of the posts 62, the adjustment being' secured by means of a set-screw 63, which enters a threaded orifice in the plate 61. The posts 62 are pivoted to the short standards 64 of the plate l() by means of screws 65. Thus the depression of the rest 59 will cause the crank 58 to rock, and the rod 60 will push the plate 6l, connecting the lower parts of the posts 62, away from the crank 58, whereupon the upper ends of the said posts 62 will approach the posts 66. One of each of the posts 66 62 carry, near the tops thereof, gear-wheels 67 68, which mesh, respectively, with the anglewheels 69 70, the latter engaging' with the beveled gears 56 57. The shafts 7l 72 of the gears 67 68 pass through bushings 7 8, set in the posts 66 62, the said bushings being held in place by screws 74. Mounted on the shafts 7l 72 are sleeves 75, each provided at its end with recesses 76, formed in its periphery. A liange or disk 77 is also carried by each of said shafts and is provided at one extremity with projections constructed and arranged to mesh with the said recess 76 and-at the other end with one or more recesses 78. The said flange serves to prevent dust or powder from getting into the bearings of my machine. A pin 79 is slipped into each of the said shafts within the recess 78, and the said pins 79 are held in place by screws 80, located in the ends of the said shafts. Upon the sleeves 75 are mounted inwardly-inclined concentric disks 83, flaring outwardly at the outer portions or circumference thereof, each pair of disks being secured together, as by screws 84, two rolls being placed on each shaft 7l 72. lVithin the converging and flaring edges of each roll formed by each pair of disks provided with radial ribs 85 I place a ring or body of yielding flexible or elastic material, as of rubber 8l, the same being ordinarily faced with flexible material, preferably consisting of leather 82, coated with emery, rottenstone, or any suitable cleaning or polishing powder. Hinged stops 54 are constructed and arranged to limit the depression of the rests 59.

` A sleeve 36 is loosely carried by the motorshaft 40, the end of which is serrated or otherwise formed, so as to serve as one member of a clutch. Another sleeve 37 is splined to the motor-shaft by means of a pin 22 of said shaft working in a slot 26 and serves as the other membei1 of the clutch. The outer end of shaft 40 is screw-threaded, and by manipulating the thumb-nut 35 the two members of thc clutch may be caused toi become engaged and the sleeve 36 rotated. Iithin the box 35S-is contained a set of gears 39, connecting in working relation the sleeve 36 and the shaft 34, sustained in a suitable manner by the base l0.

The shaft 34 carries a grindstone 28, inclosed in a combined case and knife-rest 27. The said shaft 34 also carries a brush contained within a combined case and knife-rest 3l and `also buff 30.

It is manifest that various omissions of some particulars could be made without materially affecting the essential features of my invention or the operation of the remaining parts, and I do not, therefore, wishto be limited to the specific structural details of the organization herein set forth. Obviously the elements of the structure described may be located at an angle to the plane in which they are shown. I accordingly use the words horizontah7 5 vertical, and the like in a l relative sense.

In operation the shaft 47, started in motion by means offthe motor 29, and the rolls of the supplementary shafts 7l 72 are rotated in the direction of the arrows. After inserting an article to be polished-asa knife-between the said rolls the rests 59 willupon descending cause the rock-frame 58 to rotate and the shaft 72 to approach the shaft 7l and to thereby create a flat depression on the periphery of the rolls to thoroughly clean or polish the knife-blade as it is being drawn between the rolls, the roll 98 intermediate of the cleaningroll serving to prevent thev knife from being carried too far downward when the hinged stops 54 are in open relation. When the knife is withdrawn from the machine, the parts resume their normal position. In practical use it is impracticable to push the knife-blade inward in a horizontal position, and thus cut the cleaning-rolls; but as the knife is placed in position on the rests it descends vertically in a horizontal relation while it is being drawn between the said rolls.

The polishing-'powder with which my rolls are treated falls upon the thereunder located ligure, by means of which part 100 any accumulation of said powder may be removed at will.

By flaring the edges ofthe rolldisks 83 the rubber blocks 81 ,are pressed downward into their seat when the rolls of the shaft 72 approach the other pair to which they are opposite. The rest 99 serves as a bearing to hold any article which it may be desired to hold against the periphery of the rolls. Obviously only one 'roll may be placed on each of the shafts 71 72; but I prefer the construction shown and described.v

As it is evident that many changes in the construction, form, proportion, and relative arrangement of parts'might be resorted to without departing from the spirit and scope of my invention, I would have it understood that I do not restrict myself tothe particular construction and arrangement of parts shown and described, but that such changes and equivalents may be substituted therefor and that What I claim as my invention is y l. In combination, a pair of cleaning-rolls, a pair of movable rests, a supporting-roll located between the said rests, a pair of cleaning-rolls supported by a movable carriage, and means constructed and arranged to move the carriage supporting said last-named rolls forward and thus to cause said rolls to approach the first-named rolls to increase the pressure between the rolls, upon an article being inserted between the two rolls and contacted with the said rests.

2. In a cleaning or polishing machine, a sta-v tionary roll mounted on a fixed frame, and another roll supported by a movable carriage and means constructed and arranged to be actuated by the article to be cleaned, to move the carriage supporting said roll forward and thus to cause said roll to approach the firstnamed roll and to increase the pressure between said rolls, in combination with adjusting means to regulate the different relative parallel positions of the movable roll. i

3. Inacleaning-machine, a roll, and another roll supported by a movable carriage, and means constructed and arranged to be actuated by the article to be cleaned to move the carriage supporting said roll forward and thus to 'cause said roll to approach the first-named roll and toincrease the pressure between said rolls, in combination with a horizontal part consisting of a dust-holder located between the said rolls and the bed-plate of the machine.

4. In a cleaning or polishing machine, the

combination with the frame, of a rotatory roll, a yielding roll, means to change the distance between the axes of the rolls, vertically-adjustable means to support the article to be cleaned, permanently located on opposite sides or' the rolls, means to actuate the said rolls and constructed and arranged to lie below the plane of the face of the said supporting means, to enable a blade of any length to be pushed entirely through the machine, and a removable part located under the cleaningrolls.

5. In a cleaning' or polishing machine, a stationary roll mounted on a fixed frame, in combination with another roll supported by a movable carriage, and with means constructed and arranged to be actuated by the article to be cleaned, and to move the carriage supporting said roll forward and thus cause said roll to approach the first-named roll and to increase the pressure between said rolls, upon an article being inserted between the two rolls, and with a rest or stop located adjacent to the upper portion of the periphery of said rolls.

6. In a cleaning or polishing machine, the combination,with the frame,ot' a rotatory roll, a yielding roll, means to change the distance between the axes of the rolls, vertically-adjustable means to support the article to be cleaned, permanently located on opposite sides of the rolls, means to actuate the said rolls and constructed and arranged to lie below the plane of the face of the said supporting means, to enable a blade of any length to be pushed entirely through the machine.

7. In combination, a frame provided with stationary rolls and standards 64, rests 59, rock-frame 58, rod 60, plates 6l and posts 62 carrying rolls and pivoted to the frame-standards 64.

In testimony of the foregoing specification I do hereby sign the same in the city of N ew York, county and State of New York, this 2d day of December, A. D. 1902.

HERMAN HANSEN.
